CVE-2025-2746 Scanner

Kentico Xperience 13 CMS is a widely used content management system designed for businesses and organizations to manage and publish digital content seamlessly. Developed by Kentico Software, it provides an all-in-one platform that combines web content management, online marketing, and e-commerce features. The system is renowned for its flexibility, scalability, and powerful integration capabilities with a wide range of existing business systems. Organizations leverage Kentico Xperience 13 CMS for its comprehensive toolset that enhances digital customer experiences and streamlines content workflows. The CMS's continuous updates and support cater to the evolving needs of businesses, ensuring they can deliver engaging, personalized content to their audiences.

An Authorization Bypass vulnerability allows attackers to exploit weaknesses in the authentication mechanism, granting unauthorized access to restricted areas or data. In Kentico Xperience 13 CMS, this vulnerability can be exploited with any username provided, for versions before Hotfix 173. For versions with Hotfix 173 and above but below 178, exploitation requires a valid Staging Service username. This type of vulnerability undermines the access controls put in place by developers, threatening the confidentiality, integrity, and availability of the system's data. Attackers may bypass login screens using crafted requests, making it a critical issue that needs immediate attention. Adequate authorization checks are crucial to prevent unauthorized users from gaining access to sensitive sections of the CMS.

The technical details of this vulnerability focus on the Staging Service's authentication mechanism within the Kentico Xperience 13 CMS. The vulnerability resides in how the service processes synchronization requests without properly verifying user credentials. The SOAP request handling in the affected versions allows attackers to manipulate username fields, bypassing authentication checks. Inadequate validation of the SOAP headers and the failure to enforce proper authentication controls are key to this security lapse. Exploiting this vulnerability involves sending crafted XML payloads to the Staging Service endpoint, facilitating unauthorized access to data and confidential synchronization tasks.

When exploited, the Authorization Bypass vulnerability can have severe consequences for affected systems. Malicious users could gain unauthorized access to sensitive CMS functionalities, potentially leading to unauthorized data manipulation or data theft. The bypass could also enable attackers to escalate privileges within the CMS, undermine user roles and permissions, and disable security protections. Long-term, unchecked exploitation might lead to complete system compromise, affecting the organization's reputation, customer trust, and statutory compliance obligations. Immediate remediation is essential to mitigate these risks and safeguard system integrity.
